Intent to Ship: ArrayBuffer.prototype.transfer and Friends

[Matthew Gaudet]

Hi All,

I am sending this as I intend to turn on by default the ArrayBuffer.prototype.transfer method, and friends (the detached getter, transferToFixedLength). As a result, this code will ride the 122 train to release. The patches to enable this are on Bug 1865103, and I plan to land them either tomorrow or very early next week.

This TC39 proposal is at Stage 3 of the TC39 process. 

ArrayBuffer.prototype.transfer allows expressing ownership semantics for ArrayBuffers, and provides JavaScript API to functionality that previously existed as part of HTML serialization and transfer semantics.

Meta Bug for Feature: https://bugzilla.mozilla.org/show_bug.cgi?id=1519163

Bug to enable: https://bugzilla.mozilla.org/show_bug.cgi?id=1865103

Standard: https://github.com/tc39/proposal-arraybuffer-transfer

Tests: Tested as part of test262, as well as our own implementation specific testing.

Other Browsers: Chrome shipped this as part of Chrome 114.

Thanks: Much gratitude to André Bargull who did all the heavy lifting for this proposal; I'm merely the switch-flipper-and-email-sender.
